Scalable multifunction RF system concepts for joint operations

Moreover, modular architectures provide scalability, allowing low cost upgrades and adaptability to different platforms. To achieve maximum benefit from modularity and scalability, the challenge is to define the front-end concept in such a way that it supports multiple functions and is applicable in multiple environments and platforms. This paper describes concepts for such modular systems that may be used for RF functions in maritime, airborne and land based systems. The first part discusses general scalability properties of various RF functions, the second part discusses example system concepts in a `joint' scenario (land/sea/air). The focus of this paper is on X-Ku band systems: considering essential RF functions like radar and communication, and the types of platforms in maritime, land-based and airborne operations, this frequency range provides the highest potential for application in all these domains and platforms. Conceptual designs for weapon location radar, SAR/GMTI, surveillance radar and tactical data link are presented.

In 2004 the Spoken Dutch Corpus (CGN) became available, a corpus of standard Dutch as spoken by adult natives in the Netherlands and Flanders. Owing to budget constraints, CGN does not include speech of children, non-natives, elderly people and recordings of speech produced in human-machine interactions. Since such recordings would be extremely useful for conducting research and for developing HLT applications for these specific groups of speakers of Dutch, a new project, JASMIN-CGN, was started which aims at extending CGN in different ways: by collecting a corpus of contemporary Dutch as spoken by children of different age groups, non-natives with different mother tongues and elderly people in the Netherlands and Flanders and, in addition, by collecting speech material in a communication setting that was not envisaged in CGN: human-machine interaction. We expect that the knowledge gathered from these data can be generalized to developing appropriate systems also for other speaker groups (i.e. adult natives). One third of the data will be collected in Flanders and two thirds in the Netherlands.
